WALTER MAJUS ICK, OF CLEVELAND, OHIO.

FLooasonUBBrNG MACHINE.

Application filed July 12, 1924:. Serial No. 725,560.

To all whom it may concern:

Be it known that I, WALTER MAJUsIoK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in F loor-Scrubbing Machines, of which the following is a brush and a housing carrying a buffer, the

outside diameter of which is greater than the width of the remaining portions of the mechanism, the result being that only the rubber buffer will strike pieces of furniture and the wall during the operation of the machine.

It is likewise an object toprovide a rotary scrubbing machine of this character wherein the housing and rotary brush with their associated parts may be swung upwardly upon the handle portion so as to facilitate 1 transferring the machine from place to place. a

In order that the invention and its mode of operationmay be readily understood by a persons skilled in the art, I have in the accompanying illustrative drawings, andin the following detalled description based thereon set out the: preferred embodiment of the same.

Figure 1 is a top plan view of themachine, and

Figure 2 is a side elevation of the ma chine with parts broken away and in section.

Having more particularreferenee to the drawing throughout which similar characters of reference designate like parts this improved scrubbing machine may be stated as comprising a shell or housing 5 preferably constructed of sheet metal in the form of an inverted pan, this shell having a vertical central opening adapted to mount a vertical shaft 6 upon the lower end of which is removably attached a circular rotatable brush head 7 carrying the usual bristles 8 as shown in Figure 2. A substantially inverted U-shaped bracket 9 formed of sheet metal is riveted or otherwise secured to the upper surface of the shell or housing 5, and has an opening vertically alined with the central opening in the housing 5 whereby to serve as a journal for the upper end portion of the vertical shaft 6. Carried by the shaft 6 above the bracket 9 and below or within the shell 5 is a pair of adjustable collars 10 by means of which the vertical movement of the brush is effected. It is obvious that the bristles 8 in time will wear down and through adjustment of the upper collar 10. the brush mav be lowered a disto permit eflicient operation of the wardly of the shell 5 upon a horizontally disposed bracket 14 as shown in Figure 2 of the drawings.

Obviously rotation of the brush would ordinarily splash water upon furniture and the wall in the room and in order to prevent this I arrange about the lower end or edge of the shell 5, a depending flexible rubber guard or shield 1 1, the upper edge of which terminates in an annular buffer 15 of considerable thickness, and designed to prevent scratching or otherwise marring pieces of furniture with which the machine may possibly come in contact. A pair of rearwardly diverging metal arms 16 are riveted at their fo-rward ends tothe shell 5 as shown in the drawings, the rear ends of these arms being bent and disposed in relative parallel relation and apertur'ed to receive a transverse shaft 17.

thereon and designed to function with a pair of small wheels 19 to support the aforementioned housing 5 and the rubber shield 14; as well as the motor 12 and its associated parts. The small wheels 19, are mounted upon the lower ends of depending brackets or arms 20, whose upper ends are riveted or otherwise secured intermediate the ends of the rearwardly diverging arms 16.

As shown in Figure 1 of the drawings a pair of rearwardly converging arms 21 is mounted upon the shaft 17 at points near the wheels 18 and connected to a handle This shaft 17 mounts at each end i a wheel 18 preferably having rubber. tires portion 22 at the outer end of which is a hand piece 28.

Between the aforementioned arms is disposed a water reservoir or tank 24 from which water is conveyed into the housing through a pipe or hose 25 as illustrated in. Figure 2, the flow of water through this pipe being controlled by means of a valve 26.

By reference to Figure l of the accompanying drawings it will be seen that the length of; the transverse shaft 17 is some what less than the diameter of the brush housing, or shell and consequently n operation of this mechanism the brush may be moved about the floor being scrubbed without danger of side swiping a piece of fun niture or the wall during the scrubbing operation. It is also apparent that when the operator wishes to move the scrubbing mach ne from one place to another he may if he so desires lift the rod 27 and swing the housing or shell I) and its associated parts upwardly out of engagement with the floor and retain these parts in such position through connecting the rod 2'? with the eye bolt disposed near the hand piece 23.

Applicant aware of the existence of certain scrubbing machines. but all of these are so constructed as to render their manufacture and general use prohibitive, whereas in th s mechanism all unnecessary parts have been eliminated and the structure is quite simplified.

Certan changes in the minor details of construction be resorted to and such of these changes as fall within the scope of the appended claims I consider within the spirit of my invention.

I claim:

1. A floor scrubbing machine comprising, a rotatable brush, a shell arrangedabove the brush and extending downwardly around the brush head, a shield depending from the periphery of the shell to a point adjacent the end of the brush, an annular butter arranged at the juncture of the shell and shield, a vertical central shaftcarried by the brush and extending upwardly through the shell and vertically movable therein, a mo tor arranged to rotate the shaft, a pair of rearwardly diverging arms carried by the shell, a shaft loosely journaled in the rear ends of said arms, supporting wheels carried by the shaft, a handle member fixed to the shaft and extending rearwardly therefrom, water supply tank between sad wheels and means for conducting fluid from the tank to said brush.

2. A floor scrubbing machine comprising, a rotatable brush, a shell arranged above the brush and extending downwardly around the brush head, a shield depending from the periphery of the shell to a point adjacent the end of the brush, an annular buffer arranged at the juncture of the shell and shield, a vertical central shaft carried by the brush and extending upwardly through the shell and vertically movable therein, a motor arranged to rotate the shaft, a pair of rearwardly diverging arms carried by the shell, a shaft loosely journaled in the rear ends of said arms, supporting wheels carried by the shaft, a handle member fixed to the shaft and extending rearwardly therefrom, a pair of depending brackets arranged intermediate the ends of said rearwardly diverging arms, wheels mounted at the lower ends of sad brackets to co-act with the first named wheels in supporting the set of the parts associated with the brush and shaft, tank mounted between said supporting wheels and means for conducting fluid from the tank to said brush,

A floor scrubbing machine comprising, a rotatable brush, a shell arranged above the brush and extending downwardly around the brush head and having a central opening, a vertical shaft extending through said opening and detachably connected to the brush head, a bracket carried by the shell and serving to support the upper end of said shaft, adjustable collars car ried by the shaft to permit of vertical adjustment of the brush and shaft, a motor mounted upon the shell and adapted to rotate the shaft and brush, a flexible rubber shield depending from the lower edge of the shell to a point adjacent the end of the brush, a buffer arranged at the juncture of the Shell and shield, d pair of I'Dflr-vgardly diverg'ng arms carried by the shell, a shaft j ournalcd in the rear ends of said arms supporting wheels carried by the shaft, a handle connected to the shaft, a water reservoir arranged between said arms and inn mediately above the wheel carrying shaft, means for conveying Water from the r rvoir to the rotatable brush, a pair of brackets depending from and rigidly connected to said arms, and wheels carried by said brackets for co-acting with the first named wheels to support the parts associated with the vertical shaft and rotatable brush.

In testimony whereof, I aiiix my signature.

WALTER MAJUSICK.
